Hi,
I've had a Power BI report connecting to a sharepoint folder running successfully for months and yesteday it started throwing the below error when attempting to refresh:
Details: "Microsoft.Mashup.Engine1.Library.Resources.HttpResource: Request failed:
OData Version: 3 and 4, Error: The remote server returned an error: (400) Bad Request. (Collection was modified; enumeration operation may not execute.)
I've since created a brand new report and tried connecting to the same site and the error still comes up. Other sites are working fine. There have been no significant changes to the site prior to it working the day before.
The error is occuring in Power BI Desktop, and also from the daily refresh for the same report in the Web Portal.
I'm at a loss as to how to troubleshoot this one.
Any ideas?
